Application iiled July 7,

To all 'whom it may concern.'

lBe it known that I, SAMUELk ing at Comanche, in the county of Comanche and State of Texas, have invented certain new and'useful Improvements in Spoke Tighteners, otl which the following is a specification. Y y

This invention has for its object the provision of "simple, inexpensive and 'easily Figure 1 is a sectional elevation of my iinn proved device applied wheel; f

Fig. 2 is a sectional view ot the telescopic thimbles;

Fig. 3 is a sectional view of the inner to a portion or" a z thimble taken at right angles to Fig. 2;

Fig. 11 is a plan view of the Spanner by which the device may be adjusted.

In the drawings, the reference numeral 1 indicates a portion of a telly having a wheel rim 2 secured thereon and the reference numeral 3 indicates the end o't' a spoke having a reduced portion 4L and a tenon 5 projeeting axially therefrom to engage in the telly inthe usual manner, an annular shouL der 6 being formed around the lbase. of the tenon, as shown in Fig. 1 and as will be readily understood. In carrying out my in- Y.

is claimed as new 1s:

ventioii.y I employ an inner thinible 7 which is tted tightly aroundthev reduced portion 4 ot the spoke and is provided atV its outer end with a central opening 8 Vwhereby theV thimble may iit around the tenen. At onel or more points around the opening S, .spurs or teeth 9 are provided to project inwardly and embed themselves in the end of the spoke so that rotation of the said thimble upon the spoke will be prevented. rlhe said thiinble 7 is exteriorly threaded, as indicated-at 10, and the outer thimble 11 is mounted upon the inner thimble and is interiorly threaded, as indicated at k12, so as to be` Y easily secured thereon and. adjusted longitudinally thereof. The outer end of the outer thimble 11 is also provided with a central opening 13 to litaround the tenon 'and the inner'end of the thiinble is offset, as shown 'ERWIN HES? TAND, a citizen ot' the United States, resid-j` 1922. SerialNo. 573,342.

at 14, to provide an annular enlargement or collar having openings 15 formed therethrough `at intervals tfo be engaged by av turning tool. 'n Y While any convenient tool may beV einantan *'gE;

ployed'to effect rotationA of the outer'thimble upon the Vinner tliimble, I providek a Spanner .16 having an elongated handle or lever arm 17 vand having an arcuate head 18 adapted to partly encircle thecollar` or oiset end 14 of the thmble andprovidedat its free end with an inwardly projecting lug 19 to engage any one of the openings 15 in an obvious manner. Y i

It will be readily noted that the outer ends of the two tliiinblesfit betweenl the shoulder 6 on the spoke and the Ainner circuinference of the telly and entirely fill the said space so that the spoke will iit tightly in the elly. Should the parts shrink and looseness and rattling develop in the wheel,

the Spanner 16 is engaged with theouter `thimble and the said thiinble is rotated about its longitudinal axis so that it will ride outwardly upon the inner thimble and thereby project beyond the said inner thim# ble s0 as to abut the elly and tighten the The inner thimble ,y

ting around the reduced endr of the spoke and overv the same and provided 'with in-` Vwardly projectingpiercing teeth embedding ble being exteriorly threaded, andy an outer fthimble fitting aroundland over the inner thimble with its' outer end vabutting the rim around the tenon, said outer thimble being internally threaded to. engage the inner themselves in the end of the spoke, said think i thimble and having its innerend annularly j oiset to be free vof the inner thimble and constructed to loe-engaged by a turningtool.

In testimony whereof I aiiix my'signature. SAM E. HESTAND. [L. s] I'
